Change the speed of setContentOffset:animated:?

[UIView animateWithDuration:2.0 animations:^{
    scrollView.contentOffset = CGPointMake(x, y);
}];

It works.

Setting the content offset directly did not work for me. However, wrapping setContentOffset(offset, animated: false) inside an animation block did the trick.

UIView.animate(withDuration: 0.5, animations: {
                self.tableView.setContentOffset(
               CGPoint(x: 0, y: yOffset), animated: false)
            })

I've taken nacho4d's answer and implemented the code, so I thought it would be helpful for other people coming to this question to see working code:

I added member variables to my class:

CGPoint startOffset;
CGPoint destinationOffset;
NSDate *startTime;

NSTimer *timer;

and properties:

@property (nonatomic, retain) NSDate *startTime;
@property (nonatomic, retain) NSTimer *timer;

and a timer callback:

- (void) animateScroll:(NSTimer *)timerParam
{
    const NSTimeInterval duration = 0.2;

    NSTimeInterval timeRunning = -[startTime timeIntervalSinceNow];

    if (timeRunning >= duration)
    {
        [self setContentOffset:destinationOffset animated:NO];
        [timer invalidate];
        timer = nil;
        return;
    }
    CGPoint offset = [self contentOffset];

    offset.x = startOffset.x +
        (destinationOffset.x - startOffset.x) * timeRunning / duration;

    [self setContentOffset:offset animated:NO];
}

then:

- (void) doAnimatedScrollTo:(CGPoint)offset
{
    self.startTime = [NSDate date];
    startOffset = self.contentOffset;
    destinationOffset = offset;

    if (!timer)
    {
        self.timer = [NSTimer scheduledTimerWithTimeInterval:0.01
                                                      target:self
                                                    selector:@selector(animateScroll:)
                                                    userInfo:nil
                                                     repeats:YES];
    }
}

you'd also need timer cleanup in the dealloc method. Since the timer will retain a reference to the target (self) and self has a reference to the timer, some cleanup code to cancel/destroy the timer in viewWillDisappear is likely to be a good idea too.

Any comments on the above or suggestions for improvement would be most welcome, but it is working very well with me, and solves other issues I was having with setContentOffset:animated:.
